absence of the Azygos vein associated with double superior vena cava a case report
Angiology, 1999Co-Authors: Gokhan Arslan, Can Ozkaynak, Metin Cubuk, Timur Sindel, Ersin LuleciAbstract:A rare case of absence of the Azygos vein associated with double superior vena cava is presented. Imaging findings on plain chest film and on contrast-enhanced computed tomography are described, and the embryology of Azygos and hemiAzygos veins is reviewed.

the Azygos anterior cerebral artery bypass double reimplantation technique for giant anterior communicating artery aneurysms
Journal of Neurosurgery, 2011Co-Authors: Zaman Mirzadeh, Nader Sanai, Michael T. LawtonAbstract:The authors introduce the Azygos anterior cerebral artery (ACA) bypass as an option for revascularizing distal ACA territories, as part of a strategy to trap giant anterior communicating artery (ACoA) aneurysms. In this procedure, the aneurysm is exposed with an orbitozygomatic-pterional craniotomy and distal ACA vessels are exposed with a bifrontal craniotomy. The uninvolved contralateral A(2) segment of the ACA serves as a donor vessel for a short radial artery graft. The contralateral pericallosal artery (PcaA) and the callosomarginal artery (CmaA) are connected to the graft in the interhemispheric fissure using the double reimplantation technique. Three anastomoses create an Azygos system supplying the entire ACA territory, enabling the surgeon to trap the aneurysm incompletely. Retrograde flow from the CmaA supplies the ipsilateral recurrent artery of Heubner, and the aneurysm lumen thromboses. The Azygos bypass was successfully performed to treat a 47-year-old woman with a giant, thrombotic ACoA aneurysm supplied by the A(1) segment of the left ACA, with left PcaA and CmaA originating from the aneurysm base. The authors conclude that the Azygos ACA bypass is a novel option for revascularizing PcaA and CmaA, as part of the overall treatment of giant ACoA aneurysms.

nonsaccular aneurysms of the Azygos anterior cerebral artery
Neurosurgical Focus, 2004Co-Authors: Kurtis I Auguste, Marcus L Ware, Michael T. LawtonAbstract:Object The Azygos or undivided anterior cerebral artery (ACA) is a rare variant, and aneurysms associated with this variant are particularly rare. Most reported Azygos ACA aneurysms are saccular, but the authors encountered four patients with this variant who had nonsaccular aneurysms. A review of the management of these lesions and this morphological distinction is presented. Methods A retrospective review of patients with aneurysms treated over a 6-year period identified five Type I (according to the Baptista classification) Azygos ACA lesions, of which four were nonsaccular. Aneurysms associated with other ACA variants (Baptista Types II and III) were excluded. Azygos ACA aneurysms accounted for 0.5% of all treated lesions and 1.7% of all ACA and anterior communicating artery aneurysms. One lesion in this series was located proximally at the Azygos ACA origin, and three were located distally. All four aneurysms were large (>10 mm in diameter), and two were thrombotic. All aneurysms were treated with mi...
